HEATER CONTROL MECHANISM.

To all whom it may concern. p I

' Be it known that I, ALLEN BRAN'rI vGQ HAM, a citizen of the UnitedStates, residing at Toledo, Lucas county, Ghio, have relates to atreating device Referring to the drawings: F igure 1 is a side elevationwith parts broken away of an embodiment of the invention in a'grainheater; Fig. 2 1s a fragmentary elevat on of features of the automaticcontrolling mechanism as seen from the left of Fig. 1; Fig. 3 is afragmentary plan view of the device of Fig. 1; Fig.4 is a fragmentarysection on the line IVIV Fig. 1, looking 1n the direction of the arrow;Fig. 5 is a section on the line VV F ig. 2, looking in the direction ofthe arrow, showing the parts in trip or dump position; Fig. 6is a Viewon the line VIVI Fig. 2, looking m'the direction of the arro-w, with-theparts advjusted for minimum throw in driving as controlled by thematerial receiving hopper; Fig. 7 is a fragmentary section of one of theheater ways showing a type of baflie therefor; Fig. 8 is a plan view ofthe way and baffle of F ig. 7 Fig. 9 is a fragmentary section of a wayshowing a link type of battle; and Fig. 10 is a transverse sectionthrough such way and baffie.

The jacketed treating device or heater 1 comprises the drum section 2having dia phragms 3, 1, therein connected by the ways or tubes 5. Thespace between the ways 5, the diaphragms 3, f and the drum 2 forms achamber for a heating medium as steam so that the travel of materialthrough the ways 5 may result in a treatment of such material inbringing the material to a dey sired temperature or for drying .suchmaterial.

tion with the ways5. This; hopper .7 is provided with arm 9 yieldablypoised 'by the spring 10 guided on the bolt '11 to thereby Patented Nov.30, 191 5.

yieldably maintain the hopper 7311 such,

adjusted position as may be determined by the setting of nutson the bolt11.

The material received in the hopper passing through the openings 8 andinto the ways/5 is delivered from the Ways 5 to the openings 12in linewith the fixed chutes or hoppers 13 having compartments 14 reg 1is'tering with each of'the vwaysf). These compartments are grouped'inseries for,

platform nember 16. Below thesereceiving discharging over the slats 15forming a. slotted platform-carried by the receiving slats 1 5 is theoutlet hopper 17into which 7.

the material passing between the slats '15 is discharged. The receivingplatform member 16 is provided withtra'ck extensions 18 coacting withrollers 19 carried by brackets 20niounted on the heater 1, 'so that thisglatform member is free for reciprocation to move the slatsv 15'laterally of the'series of hoppers 13 to permit spill from said hoppers13 through the slots between the slats 15 either by direct flow" or inits reciprocation to crowd the material off the slats 15. -Thisreciprocable platformzmem ber 16 has the extension or bracket 21carrying the pin 22 passing through the A slot23 .of theyoke 2 1 engagedby the rod 25 extending to the upper hopper arm 9. as to which it isheld in adjusted relation by the nuts 26. Accordingly as materialaccumulates in the'hopper 7 to overcomethe re-.

sistance of the spring 10, the rod 25 may settle down to bring, the pin22 into 'engag ing relation with each of the sides of the A-slot 23,while as the loadbecomes lighter in thefhopper 7, the spring lOmay forcethe I rod 25 upward so" that the pin 22 may have considerable play, asbetween the sides of the A-slot 23. This A slot member 23 is engaged bythe link 27 mounted on the crank 28 of the shaft 29 swung by bearingbrackets 30 fromfthe shaft 31, which shaft 31; is

mountedfo n the heater 1 by the brackets32.

The shaft 31 maybe driven continuously by the belt pulley 33, andthrough thesprocket r 3 1onthe shaft 31 drivethe sprocket chainMountedupon the upper portion ofthe 35 passing about the sprocket wheel36 on platfornr memberf15, 16.: The extent lof- 'thesereclprocation's isautomatically varied by the positionof the A slot' member 23' ascontrolled by the material supplied in the hopper 7 Fast to the shaftBlisthe bevel gear 36 in mesh with bevel gear 37 ontheupright shaft'38,which carries the 'flyball governor 39 having the collar 40 engaging thelink, 41 of the toggle links 42, 43, between the fixed bracket 44 on theheater 1 and the swinging brackets carrying'the shaft 29. With the shaft31 driven at normal speed, this speed regulated device or fly ballgovernor 39 will, throughfits ,collar 40, hold toggle 42, 43, in suchposition that the link 27 may drive the platform slats 15 back and forthunder the series of hoppers 13, as controlled by the basket; 7. However,should the mill be shut down or the drive cease for any cause, the speedcontrolling device or,

' governor 39 will act as an 'automatic dump and immediately break thetoggle 42, 43

' (Fig. 5) and thereby swing the brackets 30 and the shaft 29 towardtheh'eater 1 to force the slats 15' into such position that, there maybe material flow from the heater 1. Thisis an automatic emergencycontrol espe- .cially desirable, as in'usual stream control of materialin mills there is a drive for the ele-' vator, and if the shaft 31 isdriven in connection with the general 'run ofinachinery in themill,-stopping of the elevator would of course. stop the material supplyto the heater and should the simultaneous stop- 43 to bring the slats'15into material hold ing position. 7 p

The ways 5 are provided with baiiles or means for effecting a rolling oragitation of the grain to better insure uniformheating in theintermittent travel of the grain through the ways' The cross bar 45 overthe ways 5'may carry flexible wire cable 46 having strung thereon theplatform providing elements or' glass beads 47 positively held in alinedrelation and centrally of' the ways 5'by series of three armed centeringmeans 48 strung on the cable 46 between the platform elements orbeads47. By making the platforms 47 of glass there is acheap wearresisting material. In providing the stem 46 of flexible material thebeads may be strung thereon and the bafiie readily re 'moved from theheater or placed in posi-' tion therein even though the heater may beplacedclose to overhead structures, as ceil- 7 ing or roof: This is apoint of material advantage inpermitting the desired of the device inmany millsyl 7 Instead of the continuous cable 46 in a built up bafiie,there may be provided a seriesof U-shaped links or members, the U-shapedmember 49 being provided with centering extension means or arms50. This link 49 may be assembled through the crossshaped openin'g'51within the platform or disk 52, while the link 53 may be staggered or,oppositely assembled therethrough by springing in the'shorter arms 54which may seat upon the opposite side of the disk 52 from the arms 50.These links assembled the platforms 52 may be in staggered relation toform a flexible continuous baffle, which baf- He is flexible forinsertion into the way 5 placing and removable therefrom but ispositively held centered therein by thestaggered series of-arms 5Owh1chvhave such relation as to the disks 52 as to firmly engage the ways The'material flow in its intermittent travel through the ways 5 lands uponthe platforms or disks 5:2, is rolled thereover to present difi'erentmaterialto the walls of the ways 5 and thus insure a-uniform heating ofthe grain in its passage through the heater; i V

In the device of the disclosure there is device having heater controlmechanisms caring for such stream of material as the demands of the millmay present for uniform heating up to the capacity of the treatingdevice. The extent of the heating may be varied by controlling the steamsupply through the valve 55 and the condensation passing from the valve56. The variations in material supply at once effect the flow ratethrough the heater through the automatic adjustment of the reciprocationof the platform slats 15 as controlled by theA-slot member 23, theloading down with material increasing'the flow and accordinglyincreasing the flow rate. In addition to this automatically adjustableflow connection there is the self dumping scheme as controlled by thegovernor 3,9 precluding retention of the material in the hopper foroverloading or burning in the event of shutting down of any of thedriving devices in the mill.
